Abstract
A braking system including two brake cylinders, a pump adapted to pressurize a fluid received from a reservoir and distribute the pressurized fluid to the two brake cylinders, a solenoid-operated pressure control device disposed between the reservoir and pump and the two brake cylinders, and a controller for controlling the pressure control device for regulating the pressures in the two brake cylinder. The pump includes a piston in a cylinder bore formed so as to partially define a pump chamber that communicates (i) with the reservoir through a suction port and (ii) with the two brake cylinders through respective two delivery reports. The piston reciprocates to change the volume of the pump chamber, which in turn alternatively repeats between a suction and a delivery stroke. The pump includes a device for disconnecting the two delivery ports from each other in at least a portion of the delivery stroke of the piston.
